7 To all whom it may concern:

State of Ohio, have invented a certain new and useful Improvement in Toy. Telegraph- Sounders, of which the following is a full,

clear, and exact description, reference being had to the accompanymg drawings.

This invention relates to telegraph sounders, and has for its particularobject to produce a sounder which, while capable of operatingin a satisfactory manner, may be produced at a sufliciently low cost to enable it to be sold as a toy and at a price which will insure a large market therefor.

Further and more generally stated, the invention may be defined as consisting of the combinations of parts and elements embodied in the claims hereto annexed and illustrated in the drawings forming part hereof wherein 'Figure 1 represents a perspective view of a sounder constructed in accordance with my invention; Fig. 2 a longitudinal sectional view through the sounder base shown in Fig. 1; Fig. 3 a reduced plan view, showing the circuit connections; and Fig. 4 an enlarged sectional detail through the soundproducing part of the instrument.

Describing by reference characters the various parts illustrated herein, 1 denotes a base which may be of any suitable material, as wood. To this base there is secured a key plate 2 which may be constructed as a flat spring-metal plate secured at one end to the base and provided at its other end with a finger key 3. The plate 2 will be so shaped and the spring action thereof will be such that the free end of the plate will be elevated above the base. The free end may be conveniently retained within and confined by an inverted U-shaped strap 4 having feet 5 by which it may be secured to the base. Beneath the finger key 3 is a knob 6 carried by a pin 7 said knob and pin constituting a switch terminal, the lower end of the pin having a conductor wire a connected thereto.

011 the same base 1 there is mounted a metallic frame which may be conveniently formed into U shape having substantially parallel horizontal branch plates 8 and 9 connected by a substantially vertical plate 10. The branch plate 8 may be and preferably is considerably longer than the branch plate 9, for reasons to be stated hereinafter.

Specification of Letters Patent.

' Patented Feb. 8, 1931.6.

Serial No. 6,476.

The bottom plate 8 is provided in its upper surface with a recess 8 and the upper plate 9 is provided in its bottom with a recess 9, the recesses being vertically opposed to each other and adapted to receive the opposite ends of a tube 11, which may be of glass. Within this tube there is mounted a core 12, which is considerably shorter than the tube. The tube forms a support for a winding 13. This winding extends around'the upper portion of the tube and terminates a considerable distance short Of the lower end thereof. for the purpose of securing the proper func tioning of the core. As will appear by reference to Figs. 2 and 3, the winding 13 is part of the conductor 6 and has one end connected to the binding post lat and its other end connected to one of the pins Or screws 15 whereby the key plate 2 is secured to the base. The conductor a is connected at one end to the pin 7 and at its Opposite end to the binding post 16, and the conductors a and b may be connected with any desired source of electric energy outside the base, for instance, a dry cell.

In operation, when the finger key or button 3 is depressed, bringing the free or swinging end of the plate 2 in contact with the head or stud 6, the circuit through the solenoid winding will be closed and the core 12 will be thrown upward against the plate 9 thereby producing a sound. lVhen the pressure on the finger key 3 is relieved, the

circuit will be broken and the core 12 will drop by gravity upon the plate 8. Owing to its extent, the plate 8 provides a sounding board or plate whereby the sound produced by the impact of the core 12 against the plates 8 and 9 will be of sufficient volume to render them clearly audible.

In installing the tube 11, the plates 8 and 9 may be sprung sufficiently far apart to enable the tube to be inserted in place and the plates 8 and 9 may then be moved toward each other to clamp the tube within the recesses and between the plates.

From the foregoing description, it will be apparent that I have produced an instrument which, while possessing ample ethciency for the purpose for which it is designed, can be produced at an extremely low cost, enabling it to be sold as a toy and at a sufficiently low price to command a wide market. Among the structural features which contribute toward this result is the self-contained feature of the sound-producing element comprising the frame, 8, 9, 10, the solenoid, and the core. The construction and arrangement of the parts enables this sound producing element or member to be manufactured at a low price but without impairing the efliciency of the instrument.

Having thus described my invention, what I claim is:

1. In a sounder of the character described, the combination of a base, a sounding device comprising a substantially U-shaped metallic frame having one branch thereof secured to the base, a tube inserted between the branches of said frame, a solenoid core in said tube, and a winding extending about the upper portion of said tube.

2. In a sounder of the character described, the combination of a base, a sounding device comprising a pair of vertically spaced sounding members, a tube inserted between said members, a solenoid core in said tube, and a winding extending about said tube.

3. In a sounder of the character described,

the combination of a base, a substantially U-shaped frame having one of its parallel branches secured to said base, a tube secured between the branches of said frame, a core in said tube, a winding about said core, and an electric circuit including the winding and that is adapted to be opened and closed, the

therebeneath by gravity.

1-. In a sounder of the character described,

the combination of a base, a metallic frame supported thereon and comprising upper and lower substantially parallel branches, they lower branch having a recess-in the upper face thereof and the upper branch having a recess in the lower face thereof, a tube interposed between said branches and seated in said recesses, a core in said tube, and a winding surrounding the tube.

5. In a sounder of the character described, the combination. of a base, a metallic'frame supported thereon and comprising upper and lower substantially parallel branches, a tube clamped between said branches, a core in said tube, and a windingsurrounding the tube.

In testimony whereof, I hereunto affix my signature in the presence'of two witnesses.
